In 1963, the Bronx Zoo had an exhibit called “The Most Dangerous Animal in the World”. It was a mirror.
Back in the early 1980s, orthodontist David Marshall, from Syracuse, NY, liked to speculate about what humans would look like 2 million years in the future. Or what “Future Man” would look like, as he referred to our descendants. Based on previous trends in our evolution, he concluded that Future Man will be hairless, big-skulled, small-jawed, and have few teeth.
Dean Karnazescan can run without ever getting tired due to his exponentially high lactate threshold. He was able to run a Marathon in the south pole at -25C and run for three consecutive nights before having to stop for sleep.
Shakuntala Devi, also known as the human computer, gave the 23rd root of a 201 digit number in 50 seconds. The answer(546,372,891) was verified at the US Bureau of Standards by the UNIVAC 1101 computer, for which a special program had to be written to perform such a large calculation.
Of all the humans tested so far, everyone has contained the same DNA from 1 of at least 2 ancestors. Mitochondrial DNA being traced back matrilineally to a specific “mT-Eve,” and a Y-chromosome being traced back patrilineally to a specific “Y-chromosomal Adam.” We are not descended from a singular couple, but rather we are all seemingly descended from singular ancestors that may have lived hundreds of thousands of years apart.
700,000 year old stone tools were found in the Philippines despite the fact that known humans didn’t arrive until 600,000 years later. Researches aren’t sure how humans got there or what early hominid could have even made them.
The Sama-Bajau, a sea-faring and nomadic people, have physical adaptations that enable them to see better and dive longer underwater. It was recently discovered that they have evolved bigger spleens that provides a larger reservoir of oxygenated red blood cells.
Humans nearly went extinct, reducing to a population of only 8,800 which would qualify today as “endangered” before bouncing back.
If we assume that only 5% of all the humans that will ever be born have already been born (about 60 billion), then we can predict that 1.2 trillion humans will ever be born. Assuming that the world population stabilizes at 10 billion at a life expectancy of 80 years, it can be estimated that the remaining 1.14 trillion humans that will ever be born will be born in 9120 years. This is the Doomsday Argument.
The Voluntary Human Extinction Movement is a group that “supports human extinction primarily because… it would prevent environmental degradation.”
